LOOSE-LEAF BINDER.

To all whom it may concern:

Be it known that. I, .lnxxlxos SCOTT Mc- Conii, a citizen ot' the UnitedStates, and a resident of Dobbs Ferry, in the'county of VfestchesterVand State of' N ew York, have invented certainnew and usetulImprovements in Loose-Leaf Binders, of' which the following is aspecification, taken in con nection with the laccompanyingidrawing,which forms a part of the saine.

This invention relates to loose leaf binders and more particularly tothe binder posts, supports carried on the binder posts and means forreadily mounting and disniounting the supports.

'In the accompanying` drawing showing illustrative embodiments of thisinvention, and in which the same reference characters refer to similarparts in the several figures, Figure 1 is a longitudinal verticalsection through a loose leatl binder equipped with my invention theposts and supports being shown in side elevation, a portion of one postand a part of' one support being broken away to better illustrate theinvention. Fig. 2 is a plan view of one of the supports or index'disks.Fig. 3 is a side elevation of two sections of the post. Fig. i is a planview of the sections shown in Fie` 5. Fig. 5 is a side elevation of amodified form of post. Fie'. 6 is a cross section on line (i. of Fig. 5on an enlarged scale. Fig. T is a plan view of a modified t'orm ofsupport or index disk.

vltig. 8- is a plan view of another modified form of support o r disk.Fig. 9 is a tragmentary side elevation of a modified form l of pest.Fig. 10 is a cross section through a post such as that shown in Fig. 9,the index disks beino' shown in plan.

In the illustrative embodiments of this invention shown in the drawing,1 is a loose leaf binder having covers 2 and 3 and removable sheets 4.It is usual insuch' constructions to have a pillaror post 5 which can beextended or shortened to meet the varying requirements of the binder. Ihave formed my posts 5, it being understood that two or morev such postsmay be used, of a plurality r. f'det.acliable sections 6, (3. Eachsetion t3., Figs. land I5, has an external screw threaded portionA 7 andan internal screw threaded Specification of Letters Patent. Patenteddcbpt. 25., I 999.

portion t5, to permit the different sections 6 to be removably securedto each other. On one, or two or more ot' the sections t3 I form a fin 9which preferablv has a portion broken away, forming a recess l0 for apurpose hereinafter described, Fig. 3f

To yinsert or to remove a looseleat sheet in the'loose leaf binders nowin use entails a great amount of unnecessary labor in that a greatnumber of the sheets in the binder have to be first removed and thenthreadedback upon the post :3 to enable the new sheet, for instance, tobe locked in its proper position in the binder. save this unnecessarylabor by placing one or more supports l'l uponthe posts or piliars 5.These supports may be given any desired shape.,` but I preferably fornithem as disks,

either out of thin metal or heavy paper, or

any other suitable material. By arranging these disks at intervals uponthe posts 5 and supportingvthem in spaced relation to each other, itwill be clear that any leaves or papersl appearing. for example. aboveone of the disks 1l. will be supported by that disk, permitting the post5 to be' disconnected, by unscrewing` one of the sections 5. :forinstance, the section which may be directly be! neath the section uponwhich one ot the su pports ll may be mounted. This will permit the cover3, a part of the post 5 and all the leaves'of the binder above. theparticular support ll to be removed bodily at one operation, to permitthe insertion or withdrawal of one or more leaves at the desired placein the binder.

'I'o enable the user to readily determine approximately the place Whereit is desired to disconnect the post 5 I-preferably form index numeralsor characters upon the supports l1 shown, for insta-nce, as A A, B BandC C, in Figs. 2, 7 and l() respectively. These characters may correspondwith similar characters on the usual front index of the binder (notshown) and inthat way become ai rear index. Any desired number of thesesupports or index disks 1l may be used, one for each letter of the frontindex or for any desired number of such letters as shown in Fig. l Ihave for Apurposes of illustration ihown four such supports ll, thoughit Aisto I overcome this diiliculty andbe understood, of course thatthis nuinbei' 4 may be then given a ing the scope of my invention. Thesedisks 11 may be mou'nted in various ways upon the sections 6, 6 oftheposts 5. In Figs. 1, 2 and 3 I have shown the disk 11 provided with;aconcentric aperture 12, havin a radiating slot 13 to receive the lins 9o the different sections 6, 6. The locking means 'are so arranged uponthe dillerent sections 6, 6 that when they are firmly secured togetherall the fins 9 will register with each other, permitting a disk 11 to beslipped over the end of the ost 5 and moved down on the differentsections 6, 6'until the required location is reached opposite a recess10. The disk 11 artial rotation to secure it between the di erentsections of one tions.

of the fins 9 on one section 6, which will hold it from furtherlongitudinal movement on the post 5 in an obvious manner. I may alsoform notches 14, 14 at each end of fin 9 on one of the sections 6 sothat when two sections are brought to ether a recess 15 is formedbetween the 'ns 9 on the two sec- This ermits a wider range ofadjustment of the disks 11, it being understood, of course, that thedisks 11 may be mounted iii the grooves 15. In this form of my inventionthe disks llcaii rotate upon the different sections, but they willalways serve as supports for the leaves in the manner above describedand by arranging a plurality of designated numerals or letters upontheir surface as shown in Figs. 2,'7 'and 10, some one of these letterswill always be visible from the rear, enabling the user to tell at aglance where to disconnect the illar or post Without the aidof thefrontin' eX. In this formiof my invention also the disks act as keys-toaid in unscrewing the different sections 6. If two substantiallyadjacent disks.

11 are manipulated until their slots 13 registei' with tlie lin 9 of thesection 6 upon which each is mounted, and the disks are given a slightdownward. or upward movement so that the respective fins are brou htwithin the slots 13, it is quit'eclear that y holding one of the disks11 and rotating the other the different sections 6, 6 will be unscrewed.

In addition to'preventing a longitudinal movement of the disks upon theposts, I may also prevent their. relative rotation after they have'oncebeen properly located on the post. In Figs. 5, 6 4and 7 the posts 16 areformed with a plurality of-grooves 17 to i'it teeth 18, 18 on a support19, Fig. 7. These disks 19 can be readily slipped down on the posts 16as long as the' teeth 18, 18vregister with the grooves 17, 17. When,however, they register with the transverse grooves 20,

the teeth 18, 18 are caused to move out of the 21, forming the bottomsurface of the groove 20, is eccentric as shown on an enlarged scale inFig. 6. This eccentric may be given any desired contour, but Ipreferably forni' it so that the teeth 18, 18 will be locked upon turnof the disk 19, preventing further ielative rotation of the disk on thepost 16.

I may vary the contour of my post, forming the cross section of it, forinstance, in

until the lugs 23, 23 register with one of the v transverse grooves 25when it may be given a partialrevolution. To bind the disk to the p'ostand to prevent further rotation of the disk upon it, I preferably formwedge or cam surfaces 26 upon the post, the lugsl 23 being forced upthese surfaces 26 and securely locked to them in an obvious manner toprevent further rotation of the parts.

Having thus described this invention in connection with the severalillustrative embodiments thereof to the details of which I do not desireto be limited, what'is claimed as new and what it is desired to secureby Letters Patent is set forth in the appended claims. y
